Kenwood S-101 (1978–1980)

The Kenwood S-101 is a compact bass-reflex speaker system from the late 1970s. Kenwood was putting out a lot of affordable hi-fi separates then, and this is one of them. It's a three-way design with a 20 cm cone woofer, an 8 cm cone midrange and a 2.5 cm cone tweeter. The cabinet measures just 300 × 360 × 190 mm and weighs 5.0 kg. Impedance is 6 ohms, with 30 W continuous / 80 W max power handling. That points to entry-level systems, not high-power flagship setups.

Frequency response is rated at 80 Hz to 20,000 Hz, with crossover points at 1,500 Hz and 7,000 Hz. Sensitivity is a reasonably efficient 90 dB/W/m, which would have made it an easy load for modest receivers of the era. These are the numbers of a no-frills speaker. Nothing exotic, nothing obviously wrong.

Beyond the specifications, the documentary record is thin. There's no surviving information on original pricing, market positioning, or how reviewers or owners received it at the time. It doesn't appear to have left much of a footprint in the period press, and a search of the usual audio magazine archives turns up nothing substantial. Contemporary publications like Audio (August 1979, p.102) were advertising similar speaker components at the time. What is known is what the spec sheet says: a small, efficient, three-way Kenwood speaker built during the late 1970s, likely as a budget companion to their receivers and integrated amplifiers of the same period.

Its compact size and 6-ohm impedance make it an easy candidate for a small-room vintage system. The modest power handling means it's best paired with something in the 20-40 watt range, not a big brute of an amplifier.
